Ever since I transported myself, Ice Chester and Glommer using the Telelocator staff Ice Chester hasn't been working properly. At first things with finite durability stored inside Ice Chester were greyed out. Later they had normal colors again but I noticed that a thermal stone inside Ice Chester either stays at a neutral temperature or at most gets moderately cold. I'm assuming spoiling things don't spoil slower either anymore.
Teleport using Telelocator staff with Ice Chester that has spoiling items/items with finite durability and a thermal stone in it.
